PropertyControlGui

getLabelResource

Get the component's resource name, which getStaticLabel uses to derive
the component's label in the local language. The resource name is fixed,
and does not vary with the selected language.
Normally this method should be overriden in preference to overriding
getStaticLabel(). However where the resource name is not available or required,
getStaticLabel() may be overridden instead.

createTestElement

JMeter test components are separated into a model and a GUI
representation. The model holds the data and the GUI displays it. The GUI
class is responsible for knowing how to create and initialize with data
the model class that it knows how to display, and this method is called
when new test elements are created.

configure

A newly created gui component can be initialized with the contents of a
Test Element object by calling this method. The component is responsible
for querying the Test Element object for the relevant information to
display in its GUI.

AbstractJMeterGuiComponent provides a partial implementation of this
method, setting the name of the component and its enabled status.
Subclasses should override this method, performing their own
configuration as needed, but also calling this super-implementation.

modifyTestElement

GUI components are responsible for populating TestElements they create
with the data currently held in the GUI components. This method should
overwrite whatever data is currently in the TestElement as it is called
after a user has filled out the form elements in the gui with new
information.
